Simple, reliable, cost-effective.

For years, the Bar's leak coolant tabs have been a go-to for me. In my life, I have used them and recommended them countless times. It's the simplest option to use. They are the most cost-effective option. And, they are going to work of anything can work. Simple isn't always the best option, and often less expensive means numerous sacrifices. The tablets are so reliable though, there is no comparable option. If they required more difficult steps to use, or cost multiple times more, they would still be my first choice, every time. 26 years in the automotive repair industry, and the Bar's Leak tablets are as vital as any tool in my box.

This brand is my go-to for leaks

Works quickly and directions are simple. Used this in a few cars in the past - most recently a Jeep Grand Cherokee, and previously an old Nissan Altima. Both times the leak was sealed and it lasted until I no longer had the cars. This is the go-to brand for sealing leaks. Easy and way more affordable than a dealership.

It actually worked!

I used this product to stop a coolant leak at the timing cover on a Chevy Trailblazer with 250K miles. It was buttoned up tight in an hour with no cooling system side effects. Worked great for me. Just follow the instructions. I did hear a rumor that this product was used to stop a leak in the reactor cooling system in the nuclear submarine Nautilus...so I figured if it was good enough for them, I'd try it in my car. I'm glad I did.
